2 Claims.

This invention relates to new and useful immovements in grafting devicesand more particularly to a device for facilitating the cutting of scionsfor grafting. V

The principal object of the present invention is to provide a graftingtool whereby in cutting scions a perfectly straight cut can be obtainedand this is necessary in order to perform a satisfactory grafting job. I

. the implement.

Figure 2 is a side elevational view of the implement looking at theopposite side from that shown in Figure 1- Figure'3 is a top planview ofthe implement.

Figure 4 is a vertical section on the line 4'4 of Figure 1.

Figure 5 is a section on the line 55 of Figure 1.

Figure 6 is a perspective viewof the blade.

Figure 7 is a section on the line of Figure 1. II I Referring to thedrawings wherein like numerals designate like parts, it can be seen thatthe implement includes an elongated supporting bar 5 having a clampstructure 6 at each end portion thereof. Each clamp is generally reanglewith respect ferred to by numeral 6 and'includes a pair of jaws I, 1(see Figure 4) hingedly secured as at 8 to'the bar 5 and each having aresilient lining 9 at its inner side. A clamp screw It) serves to drawthe upper ends of the jaws together or sepa-' The purpose of theseclamps is to firmly hold the scion in place. g

A lug I I on one end of the bar 5 has a threaded opening therein for aclamp screw 12 and this clamp screw is operative against one end of thescion. l I 1 Depending from the bar 5 is a semi-circular shaped guide l3having a substantially 90 degree slot l4 therein, and depending from theintermediate portion of the bar 5 is a lug 15 which has a threadedopening therein to receive a screw [6 which passes through a slot l1 ina cutter bar securing elements 22 can be disposed for securing the bladeto the upper end of the bar. Thus it can be seen that the blade projectslaterally of the bar l8,this being readily seen in Figure 3.

Where the slot l1 intersects the slot M, a bolt 23 extends therethroughand is equipped with a nut 24. A cap plate 25 straddles thesemi-circularshaped member l3 and. the bolt 23 also passes through this cap 25. A setscrew 26 is disposed through the cap and can be screwed against one edgeof the semi-circular member I3.

The lower end of the cutter bar [8 has a han-. I dle 21 whereby thecutter bar I8 can be actu- 'ated.

An elongated blade 28 is secured to the unslotted portion of thesemi-circular shaped guide 13 and can be used for trimming branches andthe like off of scions.

It can now be seen that with the scion properly held in position by theclamp 6 and the clamp 12, the cutter bar 18 can be adjusted to thedesired angle and when this has been satisfied, the

bar l8 can be jerked downwardly and the blade 19 will cut through thescion at the desired angle, making a perfectly straight cut.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

I 1. A device for cutting scions for grafting, comprising a horizontalelongated supporting bar, spaced clamps carried, by said bar forsecuring a scion on the latter'parallel with the same, an

- connecting said cutter bar to said supportingbar l8, this cutter barl8 at its upper end being proarcuate guide rigid withand depending fromone side of said bar, an inclined cutter bar ex- I tending across saidsupporting bar and said guide and projecting above the supporting barbetween said clamps, a cutter blade carried by the upper end of saidcutter bar and projecting laterally from the latter over said supportingbar, a handle on the lower end of said cutter bar, means for pivotalmovement relative to the latter about an axis coincident with the centerof curvature may be severed between said clamps by said 'cutter blade ata desired angle upon pulling the cutter bar downwardly.

, 2. A device for cutting scions for grafting, comprising a horizontalelongated supporting bar, spaced clamps carried by said bar for securinga scion on the latter parallel with the same, an arcuate guide rigidwith and depending from one side of said bar and having an arcuate slottherein, an inclined cutter bar extending across said supporting bar andsaid guide and projecting above the supporting bar between said clamps,a cutter blade carried by the upper end of said cutter bar andprojecting laterally from the latter over said supporting bar, a handleon the lower end of said cutter bar, said cutter bar having an elongatedlongitudinal slot therein, a lug rigid with said supporting bar, a screwextending through said slot of the cutter bar and threaded into said lugfor connecting said cutter bar to said supporting bar for pivotalmovement relative to the latter about an axis coincident with the centerof curvature of said arcuate guide and for longitudinal slidi'ngmovement relative to the supporting bar, and a screw extending throughtheslot of said cutter bar and adjustable in the slot of said guide tovary the angle of the cutter bar relative to the supporting bar, wherebythe scion may be severed between said clamps by said cutter blade at adesired angle upon pulling the cutter bar downwardly.
